Title: System for the inductive transmission of message to vehicles equipped with receivers
IPC: H04B5/00
Filed: 1967-05-05
Abstract: In an inductive signalling system for vehicles travelling along a road, wherein in each direction of travel an advance loop is provided ahead of each message transmitting loop, each mobile receiver is arranged so that switching on of the receiver is prepared when a signal from the advance loop is received and is completed when a signal from the message loop also is received, the receiver being switched off when the signal from the message loop ceases. As shown in Fig. 2, the demodulator 6 in the mobile receiver normally is blocked. When a signal f 1 from the advance loop is received at ferrite aerial 3 it is amplified at 4, selected by a tuned circuit 9 and rectified at 10 to close an electronic switch 11 supplying an operating voltage U B to an amplifier 12. In the area between the advance loop and the main loop the frequency f 2 from the main loop also is received and is selected at 5, amplified at 12 and rectified at 13 to operate an electronic switch 14 unblocking the demodulator 6. The D.C. component from the demodulator 6 is amplified at 15 and operates an electronic switch 16 supplying voltage U B to the amplifier 12 to maintain the amplifier 12 in operation when the frequency f 1 is no longer present. When the frequency f 2 ceases the switch 16 is opened. In a modification, Fig. 3 (not shown), an electronic switch (17) at the output of circuit (5) controls a damping device (18) connected between circuit (9) and rectifier (10). This is arranged to prevent the unblocking of demodulator (6) when frequencies f 1 and f 2 are present together without the previous appearance of f 1 .

Title: Method and apparatus for controlling annealing furnaces
IPC: C21D9/56
Filed: 1968-03-18
Abstract: In a process and apparatus for continuously annealing metal strip the latter passes through a furnace having heating, holding, and cooling chambers the strip temperature is sensed as it leaves the heating chamber and its speed adjusted to maintain that temperature at the desired level, while the temperature of the coolant supplied to the cooling zone is adjusted to compensate for the change in strip speed. This compensation may be effected by sensing the strip temperature as it leaves the cooling chamber and correspondingly adjusting the heat supplied to the coolant. Additionally the strip temperature may be sensed near the exit of the holding chamber and the supply of heat to that chamber modified as necessary. The strip may be annealed in a controlled atmosphere, such as a nitrogen-hydrogen mixture. As illustrated, heating zone 10 and holding zone 12 are heated by radiant tubes 14 and 16 by burners fired which are under the control of temperature sensing devices 33 and 40. Strip temperature is sensed by radiation pyrometer 39 which through a potentiometer circuit controls the speed of motor 32 operating drive bridle 30. Strip temperature is also sensed at 41 thereby controlling the heat input to tubes 19 in conduit 18 through which coolant flows to pipes 17 in cooling zone 13. In a modification, heating zone 10 is subdivided into two sections the first is temperature controlled as previously described, while the heat supply to the second and shorter section is controlled from sensor 39 through a system which acts only after a time delay and to large temperature changes.

Title: Technique for anodization of thin film resistors
IPC: H01C17/26
Filed: 1968-07-16
Abstract: Film resistors 23 are adjusted to their final value by anodizing, an electrode (cathode) 27 being deposited on the substrate 21 as a film, an electrolyte being placed in contact with both the electrode film and the resistor film 23 and an anodizing current from an external source 30 being passed between the two films until the resistor reaches the required value. This value may be ascertained by a monitoring device 33. At least two interconnected resistive elements 22, 23 may be deposited on the same substrate, in which case an isolation electrode 29 may be provided. Electrode 29 is connected to earth or to a slightly negative potential to ensure that resistor 22 is not anodized during anodizing of resistor 23. Alternatively, 29 may be omitted, cathode 28 acting as an isolation electrode. The resistors may be of tantalum, aluminium, titanium, niobium, hafnium or nickel-chromium or compounds thereof (e.g. tantalum nitride) of from 350 Angstroms to 25,000 Angstroms thickness. The electrolyte used may be boric, citric, acetic or oxalic acid and may be held in a felt pad or by claws. The substrate may be ceramic. In an example an unglazed ceramic substrate was first provided with nickel-chromium-copperpalladium terminals by evaporation. After ultrasonic cleaning the substrate was then placed in a vacuum chamber containing sputtering apparatus including a tantalum carbide, the chamber being evacuated to approximately 2 Î 10-6 millimeters of mercury following which it was heated to 400 C. and nitrogen was admitted at 15 microns pressure. A D.C. voltage of 5000 volts between the tantalum cathode and the (grounded) anode was used for sputtering, a mechanical mask being provided to obtain a tantalum nitride resistor film of 1000 Angstroms thickness (14, Fig. 1, not shown) and a neighbouring film (15) to act as cathode for use in anodizing the resistive film. The electrolyte for this anodizing process was citric acid solution held in a contact pad.

Title: Method for insulating electric armature windings
IPC: B05D1/18
Filed: 1975-01-11
Abstract: A method of insulating an electrical conductor, such as a stator winding for an electric motor, is provided wherein the conductor is immersed in a thermosetting epoxy resin and then is rapidly heated by passing a direct current of pre-determined magnitude through the conductor to establish a current density in it in the range of 8,000 to 30,000 amperes per square inch of conductor cross-section. The resultant resistant heating of the conductor and the epoxy resins closely adjacent thereto causes a layer of the resin to gel around the conductor. Heating current is continued until the gelled layer is 5 to 100 mils thick, at which point the current is interrupted and the conductor is withdrawn from the varnish. The final step in the disclosed method is to bake the gelled coating of resin to finally cure it and form a hard insulating finish on the conductor.
